225 connecting rods

They ran very well. I would take about .070" off the head at his point, IF it has not been milled and you plan to run the standard composition style head gasket. You can probably mill an unmilled slant head .200". I know Charlie "accidentally" did one .125" and it was fine. I have read about people milling much more. If you have .040" off the block, .070" off the head would be .110". The extra .010" would help take up for the thicker head gasket. You might even go .085" for a total of .125". That is of course, if the head has not been milled.
